'10 ll/I14 'w/w'nt it nut/y concern.-

Be it known that 1, EDWARD RAYMOND KEL- LEY, a citizen of the UnitedStates, residing at Ashtabula, in the county of Ashtabula and State ofOhio, have invented certain new and useful Improvements in Bunsen-BurnerAttachments, of which the following is a specification.

My invention relates to improvements in gas-burners and attachments forburners of that class that is used for illuminating or cooking purposes.

The especial object of my improvements is to provide a device of thisclass that can be used in connection with a suitable lamp forilluminating purposes or with slight changes may be converted into aheating device adapted to hold small vessels.

A further object is to provide a device of this kind in which theprinciples of a Bunsen burner may be utilized and the draft controlled.

A still further object is to provide a device that will be ornamental aswell as useful and that in whole or in part may be readily moved aboutfrom place to place.

Having the aforegoing special objects and others of general utility inview, I have invented the burner and attachment illustrated in theaccompanying drawings, which form a part of this application, and inwhich- Figure 1 is an elevation of a lamp constructed according to myinvention and having a Bunsen tube connected therewith. Fig. 2 is asimilar view with the Bunsen tube and its attachments removed. Fig. 3 isan elevation of the Bunsen tube and its attachments. Fig. 4. is anelevation of the element used for connecting the Bunsen tube with thelamp proper. Fig. 5 is a top plan view of the por tion shown in Fig. 4..Fig. 6 shows in elevation one application of my improved device whenused for cooking or heating purposes. Fig. 7 is an elevation showing theBunsen burner and a regulating-shutter for same. Fig. 8 is a top planview of the parts shown in Fig. 7, showing the shutter open. Fig. 9 is asimilar view showing the shutter closed. Fig. 10 is an elevation of amodified form of lamp and attachment, and Fig. 11 is a vertical sectionof the lower part of the device shown in Fig. 10 in elevation.

Referring to the drawings in detail, A represents a circular convexmetal shell, through which are formed circular openings (4 and withwhich is connected a gas-pipe (0 having an orifice a and having-itsupper end projecting into a collar (6 formed on the outer face of theshell. The outer end of the pipe a may be suitably connected with agas-supply pipe by the usual flexible tube, as indicated in Figs. 6 and7. As shown in Figs. 1, 7, 8, and 9, there is applied to the shell A ashutter B, which conforms to the shape of the shell, so as to fitclosely thereover, and is provided with a series of scallops Z) 71 inits periphery and with openings 7)", which are adapted to register withthe holes a in the shell, and is also formed or provided with a collarZ)", which fits around the collar (0 on the shell. It will be apparentthat by turning the shutter the holes a in the shell may be partially orentirely blanked by the unperforated portions of the shutter.

For some purposes 1 may use a supplemental shutter or cap O, consistingof a metal disk adapted to fit over the shutter B and provided withholes 0', a collar 0", fitting closely the collar a and a threaded stem0, upon which may be screwed the tubular stem of the lamp D, therebyserving as a connection or coupling between the shutterBand the lamp D,so that when assembled the several parts will form a suitable standardfora gaslamp, as shown in Figs. 1 and 2. It will be understood that thegas pipe (0 extends through the shell and has its inner end bentupwardly to form a burner-tip, or it may have a suitable tip securedthereto.

In the use of the device as shown in Fig. 6 the shutter B is invertedand forms a support for a vessel, it being understood that the upper endof the pipe a serves to project the flame against the under side of thevessel.

, In the modification shown in Figs. 10 and 11 in order to provide amore ornamental standard for the lamp D and one that will prevent thelatter from being accidentally knocked over I apply to the lower portionof the tubular stem a bell-shaped base E, having portions fitting overthe shutter B and shell A and having secured to its inner wall lead orother suitable weighting material, as at e 0 In this use of my devicethe bell may or may not be secured to the shutter, and it is immaterialas to whether the openings (4 I) register or not. The lamp, includingthe bell-base, may be lifted from the pipe'a and shell A, or the pipemay be disconnected from the flexible gas-conducting tube and moved withthe lamp.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is v 1. In a device of the characterdescribed, a gas-pipe, a shell secured to said pipe and having openingstherethough, a shutter detachably secured to said shell and havingopenings therethrough adapted to register With the openings in the shelland having other portions adapted to blank the openings in the shell,said shutter also adapted to be inverted in its relation to said shell.

2. In a device of the character stated, a gaspipe, a shell securedthereto and having openings therethrough, a shutter fitting over saidshell and having openings therethrough adapted to register With theopenings in the shell, a coupling-plate having openings therethroughadapted to register With the openings in the shell and shutter aforesaidand provided with means for attaching a lamp.

In a device of the character described, a gas-pipe, a perforated shellmounted on said pipe and forming a base, a scalloped disk fit ting oversaid shell and invertibly mounted on said pipe.

4:. In a device of the character described, a perforated shell, agas-pipe passing through the center of said shell and having anair-inlet opening therein, a scalloped and perforated disk fittingloosely over said shell and invertibly mounted on said pipe.

In testimony whereof I afliX my signature in presence of two witnesses.

EDWARD RAYMOND KELLEY.
